BACKGROUND

The present invention relates generally to the field of data encryption, and more particularly to automatically discovering, changing, and encrypting passwords for systems.

A vast majority of computer programs and products are password encrypted to protect user data, user information, and the functionality of products. A password is a word or string of characters used for user authentication to prove identity or access approval to gain access to a resource and should be kept secret from those not allowed access.

With many products or programs a user's password is required to be altered or updated after, for example, predetermined time periods have expired to maintain a high level of security as the user's password might have been compromised. Some systems have a simple process for updating the password, while other systems may have complex and/or detailed procedures to update a password. The password alteration frequency can be relatively high. For example, some banks have a policy to alter production system passwords every 3-6 months as a regular practice. The passwords may need to be encrypted as well when using different encryption mechanisms to avoid tampering with them.

Complex systems are those systems which are composed of multiple middleware systems, such as application servers, databases, business process management systems and portals. Different passwords might need to be altered in one or more databases, property files, administration consoles, archive files or additional mechanisms. For example changing the database access user password is required in some systems which are using the database in a specific order. Some system have their own mechanism for storing such database passwords. The steps required to alter the passwords, if performed manually are prone to errors. These errors may cause some systems to malfunction or increase system down time.

In one embodiment, discovery function 108 performs the review automatically. In another embodiment, discovery function 108 generates a report of the success/failure of the reviews. In yet another embodiment, discovery function 108 generates a report based on a set of predetermined requirements which the review is based on. The predetermined requirements, can be, for example, the speed at which encryption function 110 can perform the procedure, the probability of success of the procedure, or amount of human interaction the procedure may require. If the review fails to meet or exceed the set of predetermined requirements, discovery function 108 may, for example, alert a third party, restart the process, and review the procedure a plurality of times more. In some embodiments, even a procedure which fails to meet the set of predetermined requirements, discovery function 108 stores the procedure in database 112.

FIG. 3 depicts a flowchart of the operational step taken by encryption function to update the password of the product within computing environment 100 of FIG. 1, in accordance with an embodiment of the present invention. Flowchart 300 depicts the updating of the product password.

In step 302, encryption function 110 identifies a password. Encryption function 110 identifies the password of a user for the product which is going to be altered. This password is supplied by, for example, the user, and a third party. In another embodiment, password program 106 requests the user's password be supplied to encryption function 110 from the user. The password may be, for example, the user's old password, the user's generated new password, a randomly generated new password for the user, a list of passwords created by the user, a password created by a third party, or additional passwords which are to replace the old password of the user. In some embodiments, the password is based on a set of predetermined characteristics which are required to be met before the password is eligible for use. Some of the characteristics may be, for example, an amount of characters, use of capitals, use of symbols, or a requirement that the password be different from a previous password. In some embodiments, encryption function 110 stores the passwords and the information related to the passwords in database 112. In some embodiments, encryption function 110's identification of the password for the product is executed automatically.

In step 304, encryption function 110 selects the product. Encryption function 110 selects the product which is going to be impacted by the alteration of the password. In some embodiments, there may be a plurality of products with a plurality of users, who have a plurality of passwords which are all to be altered. Encryption function 110 may be instructed to alter only a specific or a set of specific users, or products, or passwords within the larger grouping. In some embodiments, encryption function 110 may have a time table instructing when a specific product, user, or password, of a plurality of products, users, and passwords needs to be altered. In some embodiments, encryption function 110 performs the identification of the impacted product automatically. In one embodiment, encryption function 110 encrypts the identified impacted product in database 112 to protect the information.

In step 306, encryption function 110 retrieve the product's password alteration process. Encryption function 110 gathers the product's password alteration process from discovery function 108 or password program 106. This process can also include the expiration date of the password. In some embodiments, encryption function 110 gathers the product's password alteration process from database 112. In some embodiments, encryption function 110 performs the identification of the product's password alteration process automatically. In some embodiments, encryption function 110 identifies the product's password alteration process through the use of, for example, java, web application server (WAS), or additional encryption utilities which are capable of identifying a product's password alteration process. The utilities may be stored on server 104, but may also be stored on external locations within network 102 provided encryption function 110 may access the utilities. In one embodiment, encryption function 110 encrypts the identified password alteration process in database 112 to protect the information.

In step 308, encryption function 110 executes the products process. Encryption function 110 executes the product's process of updating the password, or inputting a new password. In some embodiments, encryption function 110 performs the execution automatically. In additional embodiments, encryption function 110 performs the execution once a set of predetermined requirements are completed. The new password may be, for example, the user's personally generated new password, an arbitrarily generated new password for the user, a list of passwords created by the user, a password created by a third party. In some embodiments, the password is created based on a predefined set of rules. This predefined set of rules specify how the password is to be altered. This alteration can be in the form of, for example, length, capital letters, numbers, symbols, and other characteristics of a password. In some embodiments, encryption function 110 has a predefined date or time which the password is changed on. This date can be, for example, the date which the password is set to expire based on the product's expiration dates, a user defined date, or a date set by password program 106.
